In modern industrial production, U-type folding machine with Programmable Logic Controller has features of fast motion and high precision, and improves the accuracy and reliability of control system of U-type folding machine.At the same time, it increases efficiency of work and produce. The paper of PLC control system and configuration monitor analyzes the working principle and control demand. According to technological requirements, I/O of U-type folding machine is counted, consisting of 8 inputs and 7outputs.According to the I/O numbers of PLC and the selection principle of memory capacity, FX2N-16MR is selected as controller of U-type folding machine. The external wiring diagram of PLC is designed. This paper designs the program ladder chart with SFC and the program is simulated by GX Developer. Finally, the configuration monitor system is designed by Monitor and Control Generated System. The simulation proves that the design effectively guarantees accuracy rapidity and security of t
